Description Blue John Fluorite Slice This exquisite Blue John fluorite slice is a rare natural specimen from the Blue John Cavern in Derbyshire, England—renowned as one of the world’s most prized and expensive varieties of fluorite. Weighing 269 grams and measuring 13.5cm W x 6.3cm H x 1.4cm D, it features the stone’s signature striped colours: rich purple-red, dark blue, and yellow tones, with a smooth polish that enhances its vitreous luster and subtle banding.

The name reportedly derives from “bleu-jaune” (French for blue-yellow), reflecting its distinctive hues.
